This means consists of pairs of tongues 58 and 6! at the ends of the webs 24 and 26 and tongues E2 and 5d at the ends of the ledges 38 and 4d. The ends of the webs 48 are provided with slots 56 that receive the tongues 58, III] and the ends of the ledges 5d are provided with slots 52 that receive the tongues 52, 6d. The outer ends of the tongues 58, 62, 62, 62 are provided with v-notches that accommodate a suitable tool for peening the tongues against web 48 and ledges 54. The webs 48 are formed with openings II! in registry with the slots 68 so that the peening tool may be engaged with the tongues 62 and 64.

The ends of the flanges 28 and 3B are notched sufiiciently, as at Na, to permit the ends of the flanges 52 to be received therein when the vertical and horizontal portions are locked together to form the window frame partially illustrated in Figure 16.

Window sections The number of window sections used in conjunction with the present invention varies according to the size of the frame and the width of the individual window sections. However, the window sections are quite similar in construction as illustrated in Figures 11, 12 and 13, 14 wherein the bottom or lower window section and the upper or top window section, respectively, are shown in detail.

The lower window section (Figures 11, 12) consists of a pair of vertical portions 22 and upper and lower horizontal portions 'M and "I5. Each of the portions It and I6 is substantially hshaped in cross-section. The portions I4 and I6 include webs I8 and 8:3, inner horizontal flanges 82 and 84, and outer horizontal flan es 8B and 88. The flange 32 is provided with an upstanding horizontal extension or portion that extends above the web I8 and whose outer face is formed with a horizontal channel 52, for receiving a resilient sealing strip R.

The flange 88 is formed with a depending horizontal extension or portion 94 that extends well below the web 85 to overlap the flange 3B of the lower frame portion 20.

Means is provided for locking the portions I2, I l and It together and this means consists of tongues and 98 at the upper and lower ends of the webs It'll of the vertical portions 12 that extend through slots I92 and IE4 adjacent the ends of the webs l8 and 82. The tongues 96 and 38 are formed with V-notches that will receive a suitable tool for peening the tongues against the webs I3, 81'].

The ends of the flanges 82, 84 are notched to permit the webs l8 and 89 to rest against the ends of the webs I00 and the ends of the inner vertical flanges I06. The outer vertical flanges IE8 of the vertical portions 12 are provided with notches N that receive the ends of the flanges 8E and 88 when the portions "I2, I l and 76 are assembled and locked together. The flanges 82, 84 and IE5 are flush with each other and the flanges 8t, 88 and IE8 are also flush with each other.

The marginal edges of a pane of glass G rest against the roughened surface I89 of the webs I8, SI] and I50 between the flanges 82 and 85, 84 and 38, and I2 and IE8. The flanges 82, 86, 84, 88, I2 and IE8 are each provided with longitudinal lips I I6. Retaining strips or wedges W are forced under the lips III] and against the pane of glass and the flanges 86, 88 and I08 to retain the glass relative to the sash and against the flanges 82, 84 and I116.

The upper sash or window section as shown in Figures 13 and 14 comprises a pair of vertical portions II l and upper and lower horizontal portions H6 and H8. The upper and lower portions IIB and II8 include webs I25 and I22, inner horizontal flanges I24 and I26, and outer horizontal flanges I23 and I30.

The flange I30 is provided with a depending horizontal extension I32 that extends below the web I22 and which terminates in an offset I34 that will overlap the flange 8B of the portion 14 of the lower window section. Another flange I36 depends from the web I22 and will abut the sealing strip mounted in the channel 92 of the lower window section.

A horizontal offset extension I40 for the flange I28 rises from the web I20 for overlapping the flange 28 of the frame portion I8 and a horizontal extension I38 for the flange I215 extends above the web I28 for engagin the sealing strip carried by the channel M! of the frame portion III.

The vertical portions I It include Webs I42 and inner and outer vertical flanges I44 and I i-6, and

the flanges I46 are provided with vertical extensions I48 that will engage the strips carried by the vertical channels 56 of the frame portions or stiles 22.

The ends of the flanges I24 and I26 are notched to permit the webs I20 and I22 to rest against the upper and lower ends of the webs I 42 and flanges I44. The flanges I48 are formed with notches N2 that receive the ends of flanges I20 and I20.

Tongues I50 and I52 are provided at the upper and lower ends of the webs I42 and extend through slots I54 and I56 adjacent the ends of the webs I20 and I22. These tongues are provided with V-notches that receive a tool for peening the tongues against the webs I20 and I22 to lock the portions II4, I I6 and I I8 together.

A pane of glass GI rests against the roughened surfaces I09 of webs I20, I22 and I42 between the flanges I28 and I24, I26 and I30, and I44 and I46. Lips II0 are provided on the flanges I28, I30 and I 46 and retainer strips W2 are forced under the lips I l0 and retain the glass GI against the flanges I24, I26 and I44.

Reference is directed to Figure 6 wherein there is disclosed a deflector or rain shield I 58 that overhangs the upper window section and which is a part of a horizontal plate I60. The plate I60 is formed with a channel I62 at its upper edge that receives the upper edge of the flange 28 and the lower end of the plate I60 is secured against the inner face of the flange I40.

Window section mount Channel brackets I64 are positioned in the vertical portions 22 and include vertical slots I66 that receive fasteners I68. The fasteners I 68 are threaded in apertures provided in the flanges 48 as shown in Figures 2 and 8. Ribs I on the brackets I64 coact with the webs of the brackets in defining channels that slidably receive vertical rack bars I'I2.

Pivots I14 are secured to and project horizontally from the rack bars I12 and these pivots support the inner ends of links I16 whose outer ends are fixed to the Webs I00 and I42 of the upper and lower window sections behind the flanges I08.

Pitmans I18 are terminally secured to the brackets I64 and the upper ends of the webs I00 and I42 so that as the rack bars are raised the window sections will be swung upwardly to their open position.

Operator Means is provided for imparting vertical sliding movement to the rack bars and this means consists of a central bearing I82 secured to the web 26 of the frame bottom 20 that rotatably supports the adjacent inner ends of a pair of horizontal shafts I84. End bearings I86 mounted within the portion 20 rotatably support the outer ends of the shafts I04. The outer ends of the shafts I B4 support beveled gears I88 that mesh with beveled gears I00 at the lower ends of two vertical shafts I02 which are mounted in the vertical portions 22 of the frame.

The upper ends of the vertical shafts I92 are rotatably supported in combined bearing and guide members I94 fixed within the portions 22 and support gears or worms I96 that mesh with the rack bars H2. The members I94 are formed with vertical channels that slidably receive the lower ends of the rack bars.

The central portion of the web 42 rotatably supports the shaft I98 of a crank handle 200. The shaft I98 carries a beveled gear 202 that meshes with beveled gears 204 on the inner ends of the shafts I84 so that as the crank handle is rotated in one direction the window sections will be raised whereas a rotation of the crank handle in the opposite direction will effect a lowering of the window sections and the rack bars.

In practical use of the present invention, when the window sections are in their closed position the flanges I08, I48 and the ends of the flanges 94, I32 rest against the sealing strips carried by the channels 56, the flange 40 overlaps the plate I60, the flange I38 rests against the strip carried by the channel 40, the flange I36 rests against the strip carried by channel 90, the flange I34 overlaps the flange 86, the flange 94 overlaps the flange 30 and the flange 34, 42 rests against the strip carried by the channel 46.

As the crank handle 200 is manually operated, the rack bars II2 will slide vertically to impart swinging movement to the windows. The rack bars may be locked in a vertically adjusted position by any suitable means such as a lock preventing rotation of the crank handle.

Obviously, intermediate window sections may be mounted between the upper and lower window sections described with the upper horizontal portions of the auxiliary window sections constructed as the portion I4 and with the lower horizontal portions of the auxiliary window sections constructed similar to the portion I It.

It should be observed that the frame and window sash forming members or portions are of minimum width and that the window operator is concealed in the frame. Also the brackets I64 are vertically adjustable to compensate for shrinkage or warping of the window sections.

The window structure thus described may be shipped in sections and readily assembled on the job in a minimum time with few tools and requiring few workmen. Corking or a sealing compound may be employed about the frame and the opening in the building structure in which the frame is mounted.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

A window operator mechanism for windows of the type including a window frame and a plurality of sashes pivotally carried by a window frame for movement by said window operator mechanism, said window operator mechanism comprising a transversely extending horizontal shaft, means connected to said horizontal shaft for effecting selective rotation and positioning thereof, vertical shafts mounted at opposite ends of said horizontal shaft, intermeshing gears carried by adjacent ends of said vertical and horizontal shafts to effect rotation of said vertical shaft in response to rotation of said horizontal shaft, slide bars mounted for vertical sliding movement in alignment with said vertical shafts, each of said slide bars having a rack portion facing an adjacent one of said vertical shafts, worm gears on upper ends of said vertical shafts intermeshed with said rack portions to effect vertical movement of said slide bars in response to rotation of said horizontal shaft, said slide bars being adapted to be pivotally connected to a plurality of window sashes.
